Objectives: Chronic continuous dentoalveolar pain (CCDAP) is a new term for chronic pain around teeth. Quantitative sensory testing (QST) has shown promise as a tool for studying mechanisms of pain conditions. Aims: 1) compare sensory parameter values in CCDAP patients and symptom-free controls; and 2) characterize the somatosensory profile of patients with CCDAP. Methods: The German Neuropathic Pain QST protocol of 13 somatosensory function tests was adapted for intraoral use. Cases with CCDAP from tertiary care clinics were tested along with symptom-free controls. QST was performed intra-orally on symptomatic facial gingiva, asymptomatic contralateral site, and non-trigeminal site (thumb). Means and standard deviations were compared between symptomatic and asymptomatic sites within cases and with controls. Results: Interim analyses of 17 controls and 13 cases showed a mean age of 37 years for controls and 55 for cases. At the thumb, significant differences (p < 0.05) between cases/controls were apparent for pressure pain threshold (PPT) 353 vs. 453 kPa; mechanical pain threshold (MPT) 75 vs. 161 mN; and cold pain threshold (CPT) 8.4 vs. 2.8 C, all showing cases more sensitive. At the painful gingival site, significant differences between cases/controls existed for: CPT 17.4 vs. 8.1 C; HPT 44 vs. 49 C; MPT 55 vs. 154 mN; and PPT 106 vs. 172 kPa. Non-painful parameters, such as cold and warm detection threshold were generally not significantly different between cases/controls at thumb and painful gingival sites. Among cases only, comparing painful to nonpainful side, MPT was 55 vs. 96 mN; mechanical pain sensitivity 4.7 vs. 3.0; PPT 106 vs. 122 kPa, all more sensitive on the painful site. Conclusions: These results suggest that CCDAP patients are more sensitive to multiple modalities of painful stimulation at both non-trigeminal and trigeminal sites, and may be exhibiting a trigeminal neuropathy with gain in function.
